Abstract
Digital holography is an imaging technique that enables a 3-dimensional reconstruction of both the amplitude and phase of an electromagnetic field after its interaction with an object. Second harmonic generation being a coherent process, it can also be used to generate interferences and holograms. Since collagen molecules exhibit a significant second order response, we apply harmonic holography to porcine cornea samples to obtain single-shot measurements of the 3D spatial distribution of the collagen fibers. In addition, we propose polarization multiplexing to study the polarization dependence of the sample response.
